intctl(1M) intctl(1M)
-r file Restore the system interrupt configuration from the specified file, file. The interrupt
configuration is restored only if all the interface cards and CPUs referenced in the saved
configuration file are still present on the system and the CPUs are in the same state as in
the saved configuration. If new cards and new CPUs are added to the system,
intctl
will continue to restore the interrupt configuration as long as the old configuration has
not changed.
intctl will fail to restore the interrupt configuration if the file permission
is not 0600.
In restoring the system configuration, the
intctl command will assign interrupts from
the interface cards to the CPUs as specified in the file.
-s file Save the system interrupt configuration to the specified file, file, with file permission
0600. If the file exists, the content of the file will be overwritten and the file permissions
will be changed to 0600. The
intctl command will store the interrupt information of
all the CPUs on the system. This file can be used to restore the interrupt configuration of
the system later using the using the -r
option.
-w Force migration of interrupts without asking for user input. This option can be used only
with the -M option or the -b
option. When -w is used with the -M option, the migration
of interrupts is forced even if warnings are found during migration verification. When
-w is used with the -b
option, migrations occur without asking for confirmation. When
the
-w option is not specified, intctl displays a prompt, asking for user confirmation.
Interrupt Configuration Display
The interrupt configuration can be displayed sorted by CPU ID (by specifying
intctl -p
) or sorted by
interface card hardware path (by specifying
intctl -H hw_path).
By default, the command displays interrupt information about all the interface cards on the system.
Here is a sample interrupt configuration display, and the fields are explained below.
NOTE: For cards using two or more interrupts, only the CPU and interrupt information is displayed
from the second interrupt entry. The
-F option can be used to get all the information repeated for every
interrupt entry (which is same as what previous version of intctl displayed for cards using multiple
interrupts).

hw path A numerical string of hardware components separated by slash (/), to represent a bus
converter. The first component in the hardware path is the cell (for a cell based system)
or the system bus adapter (for a non-cell based system). The system bus adapter is fol-
lowed by the address of the local bus adapter and the interface card. Subsequent
numbers are separated by periods (.). Each number represents the location of a
hardware component on the path of the device.
class The class of the interface card, such as: lan, tty, ext_bus.
drv name The driver associated with the card.
card cell The cell number of the cell to which the card is connected.
cpu ID An integer value representing the identity of the CPU to which the card’s interrupt is
assigned.
